Figure 1 shows a heating arrangement 10 comprising a first article in the form of a pipe 12 carrying a material. The heating arrangement 10 further includes a second article in the form of a heating tube 14 through which a heating fluid flows. The heating arrangement 10 heats the material in the pipe 12.

The heating arrangement 10 further includes a plurality of securing assemblies 16 for securing the heating tube 14 to the pipe 12. The securing assemblies 16 are spaced along the pipe 12.

Each securing assembly 16 comprises an elongate member 18 extending around the pipe 12. The elongate member 18 is in the form of a cable, wire, wire rope or the like.

Each securing assembly 16 further includes a connecting device 20 for connecting the opposite end regions 19 of the elongate member 18 to each other. In one embodiment of the invention, shown in Figure 21, the connecting device 20 comprises a body 22 having a cap 23. The connecting device 20 further includes clamping mechanisms 42 in the body 22 for clamping the opposite end regions 19 of the elongate member 18.

Each clamping mechanism 42 comprises a clamping member 43 for clamping the end regions 19 of the elongate member 18. The body 22 further includes two clamping walls 44 and two reaction walls 46. Each reaction wall 46 converges toward a respective one of the clamping walls 44 to define a narrowing gap therebetween.

The clamping mechanism 42 also has two resilient urging members 48 (shown schematically in Figure 21). Each urging member 48 is arranged to urge a respective one of the clamping members into the narrowing gap between the respective clamping and reaction walls 44, 46.

Each securing assembly 16 also includes an attaching arrangement in the form of a clip 24 for attaching the heating tube 14 to the elongate member 18. One of the clips 24 is shown in detail in Figures 21 to 24. The clip 24 comprises a retaining formation 26 for retaining the heating tube 14, and two holding members 28 for holding the elongate member 18. The holding members 28 are arranged on opposite sides of the retaining formation 26.

The retaining formation 26 comprises a central portion 30 and two deformable gripping members 32 extending from the central portion 30. The gripping members 32 are deformable towards each other to grip the heating tube 14, as indicated by the arrows A in Figure 18.

The attaching arrangement further includes a substantially flat insertion portion 34 for insertion between the elongate member 18 and the pipe 12. The insertion portion 34 is in the form of a segment of a circle, such as a semi-circle. The insertion portion 34 extends from the central portion 30.

The connecting device 20 further includes a tightening arrangement for tightening the elongate member 18 against the pipe 12. The connecting device 20 may comprise the tightening arrangement.

The tightening arrangement comprise a threaded spacing member 36 screwed into a hole 37 defined in the body 22. The spacing member 36 comprises a substantially flat head portion 38 and a threaded portion 39. The spacing member 36 extends from the body 22 so that the head portion 38 may engage the pipe 12.

Screwing the spacing member 36 through the body 22 moves the head portion 38 into engagement with the pipe 12, and tightens the head portion 38 against the pipe 12. The tightening of the head portion 38 against the pipe 12 has the effect of moving the body 22 away from the pipe 12 as shown by the arrows B in Figures 19 and 20, thereby tightening the elongate member 18 against the pipe 12.

In order to mount the securing assembly 16 on the pipe 12, the connecting device 20 is arranged on the pipe 12, and the elongate member 18 arranged around the pipe 12 (see Figures 2 to 5). The opposite end regions 19 of the elongate member 18 are then pushed through the connecting device 20 (see Figures 6 to 8).

The elongate member 18 is spaced from the pipe 12 at the connecting device 20. This spacing allows the insertion portion 34 to be inserted between the elongate member 18 and the pipe 12 (see Figures 9 and 10). Thereafter, the holding members 28 are inserted between the elongate member 18 and the pipe 12 (see Figures 11 and 12).

The elongate member 18 is then introduced into the holding members 28, so that the elongate member 18 is held by the holding members 28 (see Figures 13 and 14). The clip 24 is then moved to a position at which the heating tube 14 will extend (see Figures 15 and 18).

The elongate member 18 may then be tightened against the body 22 by screwing the spacing member 36 through the body 22 so that the head portion 38 engages the pipe 12 (see Figures 19 and 20). This moves the body 22 away from the pipe 12 to tighten the elongate member 18 around the pipe 12. Tightening the elongate member 18 against the pipe 12 has the effect of fastening the clip 24 against the pipe 12.

Thus, the spacing member 36 provides the advantage in the embodiment described herein that the clip 24 is fastened in position. It provides the additional advantage that the elongate member 18 can be released thereby allowing a further clip 24 to be added if, for example, a further heating tube 14 is to be installed.

The above steps are then repeated for further securing assemblies 16 to mount a plurality of the securing assemblies 16 on the pipe 12 in a spaced relationship from each other (see Figure 17).

When a desired number of the securing assemblies 16 are mounted on the pipe 12, the heating tube 14 may be arranged thereon and secured to the pipe 12 by means of the clips 24.

The heating tube 14 is arranged between the gripping members 32 of each clip 24. The gripping members 32 are deformed into gripping engagement with the heating tube 14 to grip the heating tube 14 and, thereby, secure the heating tube 14 to the pipe 12.

There is thus described a securing assembly 16 and a heating arrangement 10 which secure a heating tube 14 to a pipe 12, and which includes a tightening arrangement 36 for fastening a clip 24 to the pipe 12. The tightening arrangement 36 can be released to allow the clip 24 to be removed or a further clip 24 to be added.

Various modifications can be made without departing from the scope of the invention.

A modified version of the connecting device, generally designated 120, is shown in Figures 26 to 37. The connecting device 120 comprises two connecting arrangements 122 attached to each other by a tightening arrangement in the form of a resilient spacing member 124.

The resilient spacing member 124 is provided to space the connecting arrangements 122 from each other, and to allow the connecting arrangements to be moved towards each other. In the embodiment shown, the spacing member 124 comprises a compression spring, and defines a central region 124A.

Each of the connecting arrangements 122 comprises a body 125 and a clamping mechanism 126. Each body 125 houses a respective clamping mechanism 126.

Each clamping mechanism 126 comprises a clamping member 128 for clamping a respective one of the end regions 19 of the elongate member 18. In the embodiment shown, the clamping members 128 are in the form of rollers, but it will be appreciated that each clamping member 128 could be any other suitable clamping member, such as a ball or a wedge.

Each clamping mechanism further includes an urging member 130 to urge the clamping member 128 into clamping engagement with the respective end region 19 of the elongate member 18. As shown in Figures 28, 31 and 34, the urging members 130 are in the form of compression springs Each connecting arrangement 122 further includes a respective clamping formation in the form of a clamping wall 132 of the body 125. The clamping members 128 clamp the end region 19 of each elongate member 18 against the clamping wall 132. Each urging member 130 extends along the respective clamping wall 132.

Each connecting device 120 further includes a reaction formation in the form of a reaction wall 134 of the respective body 125. The reaction wall 134 converges towards the clamping wall 132 to provide a narrowing gap therebetween.

The clamping member 128 clamps the elongate member 18 in the gap between the clamping wall 132 and the reaction wall 134. When the elongate member 18 is so clamped, the clamping member 128 is itself clamped against the reaction wall 134.

Pulling the clamping member 128 and the elongate member 18 into the narrowing gap has the effect of increasing the clamping force on the elongate member 18.

Each of the bodies 125 defines an entrance opening 136 through which the respective end region 19 of the elongate member can be inserted to be clamped by the clamping mechanism 126. The connecting arrangements 122 are arranged so that the entrance opening 136 of each connecting arrangement 122 faces the other connecting arrangement 122.

Each of the bodies 125 further defines an exit opening 138, through which the end region 19 of the elongate member 18 exits the body 125.

Each of the connecting arrangements 122 further includes a guide member 140 defining a through bore 142, through which the respective end region 19 of the elongate member 18 extends. The through bore 142 of each connecting arrangement 122 is aligned with the entrance opening 136 of the other connecting arrangement 122.

In use, the connecting device 120 is arranged on the pipe 12, and the opposite end regions 19 of the elongate member 18 connected thereto, as follows.

Referring to Figures 26 to 28, the end regions 19 of the elongate member 18 are presented to the respective guide members 140.

Then, as shown in Figures 29 to 31, the end regions 19 are inserted in the direction of the arrows C in Figure 31, through the bores 142 in the guide members 140 of each of the bodies 125. When so inserted the end regions 19 are received along the central region 124A of the spacing member 124. Thus, each of the end regions 19 is pushed from a respective one of the connecting arrangements 122 towards the entrance opening 136 of the other connecting arrangement 122.

Figures 32 to 34 show the further insertion of each of the end regions 19 in the same direction as indicated by the arrows C in Figure 31. The end regions 19 are pushed through the entrance openings 136 of the respective connecting arrangements 122. The end regions 19 engage the clamping members 128 to push each of the clamping members 128 away from the respective entrance openings 136 along the clamping wall 132, thereby allowing each end region 19 to be pushed through the respective body 125 to exit therefrom via the exit opening 134.

When the end regions 19 have been fully inserted into the connecting arrangements 122, both end regions 19 can then be pulled in the opposite direction, indicated by the arrows D in Figure 34. This has the effect of pulling the clamping members 128 into the narrowing gaps between the clamping walls 132 and the reactions walls 134. This has the effect of increasing the clamping force on the clamping members 128, thereby ensuring the elongate member 18 is tightly wound around the pipe 12.

Figures 35 and 36 show the elongate member 18 wound around the pipe 15. The elongate member is held tightly around the pipe 15 by the connecting device 120. The spacing member 124 pushes the connecting arrangements 122 away from each other to maintain the elongate member 18 tight around the pipe 12.

Referring to Figure 37, the elongate member 18 can be loosened from its tight engagement around the pipe 12 by moving the connecting arrangements 122 towards each other, as indicated by the arrows D, to compress the spacing member 124.

When the elongate member 18 is loosened, one or more of the clips 24 can be arranged between the elongate member 18 and the pipe 12. The connecting arrangements 122 can then be released to allow them to return to their positions shown in Figures 34 and 35. This causes the connecting device 120 to retighten the elongate member 18 around the pipe 12, thereby fastening the, or each, clip 24 against the pipe 12.

The bodies 125 are not limited to the shapes shown in the earlier Figures. Fig 38 illustrates an example in which one or both of the bodies 125 is cylindrical in cross-section. The outer diameters of the bodies 125 may be approximately the same as the outer diameter of the spacing member 124 therebetween.

Figs 39-41 introduce additional examples of the clip 24.

Firstly, Figs 39-41 illustrate that the holding members 28 could be different. The holding members 28 of Figs 39-41 can hold the elongate member 18 in two different ways, referred to as a 'bridge' technique and a 'return' technique respectively.

The 'bridge' technique is fundamentally similar to how Figs 22-25 work. The elongate member 18 passes under a first holding member 28, passes through a wire aperture 29 to an upper surface of the insertion portion 34, then passes through another wire aperture 29 to extend under a second holding member 28. The holding members 28 may be locally deformed at the wire apertures 29.

The 'return' technique requires the elongate holding members 28 to be longer than those shown in Figs 22-25, and deformable so that they can be deformed over the elongate member 18 in a similar manner to the gripping members 32. The cantilever length 'L' of a holding member 28 may be longer than 50% of the circumference of the elongate member 18, or longer than the total circumference of the elongate member 18. In an example, the holding members 28 can be folded by an obtuse angle so that their ends are closer the gripping members 32. A local thin portion of the elongate members 18 at the wire apertures 29 may act as a hinge point for this deformation.

In a further alternative embodiment, the wire apertures 29 can be omitted so that only the 'return' technique can be used.

Figs 39-41 also illustrate different implementations of the gripping members 32 than Figs 22-25.

Fig 39 demonstrates that a single gripping member 32 could be used, instead of two gripping members.

Fig 40 demonstrates that three gripping members 32 could be used, instead of two gripping members. Two gripping members 32 are located to one side of the heating tube 14, and the third gripping member 32 is located to the other side of the heating tube 14. The third gripping member 32 is centrally located, with the first and second gripping members 32 to either side of the third gripping member 32.

Fig 41 is a variant of Figs 22-25 in which the two gripping members 32 are not offset from each other. To prevent interference, the first gripping member 32 is narrower than the second gripping member 32 and the second gripping member 32 is wider and comprises an aperture 33 that is wider than the first gripping member 32. Therefore, the first gripping member 32 can be folded over the heating tube 14 and through the aperture 33 of the second gripping member 32, and the second gripping member 32 can be folded over the heating tube 14 without colliding with the first gripping member 32.

In some examples of the disclosure, the entire clip 24 may be supplied in a planar shape prior to deformation of the holding member(s) 28 and prior to deformation of the gripping member(s) 32. The planar shape may comprise a flat shape. The clip 24 may be a sheet of material such as metal, thin enough for the members 28, 32 to be deformed by a user. The flatness of the clip 24 enables the clip 24 to be mass produced, for example by laser cutting, and enables the clip 24 to take up minimal space prior to installation.
